COLLAPSIIBLE DRINKING-CUP.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed September 25, 1911. Serial No. 651,087.

To all whom it may concern:

Be it known that I, SAMUEL CURTIS, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulCollapsible Drinking-Cup, of which the following is such a full, clear,and exact description as will enable any one skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

Heretofore, collapsible drinking cups have usually been of thetelescoping type in which the body or cup proper is formed of aplurality of metallic rings telescoping one within another. Oneobjection to cups of this type is their weight and bulk, and anotherobjection is that the telescoping rings are very liable to becomeinjured so that they will fail to make a water tight joint, and the cupthus becomes useless.

The object of my invention is to provide a collapsible drinking cup inwhich the objectionable features referred to will be overcome. This Iaccomplish by forming the body or cup proper of collapsible water proofmaterial such as thin sheet rubber,

and providing means for supporting the cup in its extended position, aswill be fully pointed out hereinafter.

In the accompanying drawings, which illustrate one form of cup made inaccordance with my invention, Figure 1 is a vertical central section;Fig. 2 is a side elevation; Fig. 3 is a top plan view, the body of thecup being folded but the lid being in raised position, and Fig. 4 is aside eleva tion of the cup in its folded or collapsed position.

Like numerals of reference refer to similar parts in the several viewsof the drawings.

5 is the body or cup proper. This body is formed of flexible water proofmaterial, preferably thin sheet rubber. The bottom of the body 5 issecured to a base 6 by having its edges clamped between said base a disk7 corresponding in size to the bottom of the body. This disk 7 may besecured to the base 6 in any suitable manner. In the drawings, I haveshown a screw 8 for securing these parts together. The upper end of thebody 5 carries a supporting ring 9 from which projects an H-shapedmember 10 for supporting the top of the body from the lid, as will behereinafter described. The base 6 is provided atdiametrically oppositepoints with a pair of enlargements 11 and 12, respectively, each formingreceptacles. Within the receptacle 11 is a coil spring 13 whichsurrounds a rod 14 which serves as a pivot to hinge the lid 15 to thebase 6. This lid 15 corresponds in shape with the base 6 and is providedwith a slot 16 adapted to receive the H-shaped projection 10hereinbefore referred to, when the cup is in its extended position. Inorder to fold the cup the projection 10 is disengaged from the slot 16and the supporting ring 10 is rotated through one-half a revolution totwist and fold the body 5 so that the body will collapse within the base6 and the projection 10 will come within the receptacle 12, as shown inFig. 8. The lid is then folded down and held in its closed position bymeans of a spring detent 17, as shown in Fig. 4.

It will be evident that my cup is very light and compact inconstruction, and that there is practically no liability of the body orcup proper becoming injured so as to allow leakage.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:

1. In a collapsible cup, the combination with a body of flexiblematerial, of a base to which the bottom of said body is secured, and alid for said base adapted to support the top of said body.

2. In a collapsible cup, the combination with a body of flexiblematerial, of a base to which the bottom of said cup is secured, and apivoted lid for said base adapted to support the top of said oody.

3. In a flexible cup, the combination with a body of flexible material,of a base to which the bottom of said body is secured, a supporting ringcarried by the upper end of said body, a lid pivoted to said base, andmeans for detachably securing said lid to said supporting rin 4. In acollapsible cup, the combination with a body of flexible material, of abase to which the bottom of said body is secured said base havingenlargements forming receptacles at diametrically opposite points, a lidpivoted to said base, a spring in one of said receptacles for movingsaid lid into a position substantially at right angles to the base, asupporting ring carried by the my hand and aifixed lny seal in thepresence upper end of said body, and a pro ection of the two subserlblngWitnesses.

carried by said rin and adapted to en a 'e V with said lid saidprojection being adapt d SAMUEL GURFIIS' to enter the other of saidreceptacles When Witnesses: the body is rotated to fold the same. W. A.ALEXANDER,

In testimony whereof, I have hereunto set B. L. CROWLEY.
